3M™ Highland™ Twist-On Electrical Spring Connector is used to connect 2 or more copper conductor ends in a pigtail application. Its vinyl construction provides good thermal insulation, making it perfect for use in electrical applications that require safety. A spring mechanism enables them to spin on quickly and tighten down easily onto the wire end.
3M™ Highland™ Twist-On Electrical Spring Connector performs a spring action that delivers uniform holding power while connecting the conductors. The spring inside the connector has a durable steel construction with a corrosion-resistant coating. It offers enough space to accommodate a wide range of solid or stranded copper wires. The color-coded connector ensures easy identification of wires to be connected. The shell of the connector is designed to withstand high temperatures, allowing for use in the toughest environments. UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
